Definitions

  • the invention relates to a clamping element according to the preamble of claim 1.
  • a clamping element according to the invention or a connecting terminal equipped with it is particularly, but in no way exclusively intended for connecting reactors and transformers.
  • the coils of these components are generally produced using so-called enamelled wires which have an immersion lacquer layer for insulation.
  • the insulation layer in the connection area must be removed to connect the coil formers.
  • stripping the wires to be connected is time-consuming and generally hinders series production.
  • Terminals are known in many ways from the prior art. In addition to screwable terminals, such terminals are also known which clamp the wire end to be connected and thus connect them to the terminal in an electrically conductive and non-positive manner. However, in addition to the stripping of the line end to be connected which is necessary, the known connection terminals also have the disadvantage that these terminals are only suitable for a specific cross section of the electrical conductors to be connected.
  • the known clamping elements or terminals generally have a metallic clamping element in which a clamping slot is provided for receiving the end section of the line to be contacted. By compressing the clamping element and the end section of the line to be contacted, the latter is connected to the clamping element in an electrically conductive and non-positive manner.
  • the cross sections of the connectable electrical lines only have a narrow tolerance range which is related to the dimensions of the clamping slot.
  • a clamping element of the type specified at the outset is described in DE-A-3 601 788.
  • This known clamping element is formed by an integrally made of a U-shaped or wavy-folded, electrically conductive, surface-like substrate with longitudinal sections running essentially in the longitudinal direction of the line section to be contacted and cross sections running essentially transversely to the longitudinal direction of the line section to be contacted .
  • clamping slots are arranged which extend transversely to the longitudinal direction of the line to be connected and into which the section of the line to be contacted can be inserted, whereby by compressing the clamping element and the line section to be contacted, these are both conductive and non-positive in the area of the clamping slots get connected.
  • the clamping slots have different opening cross-sections that decrease in the direction of the inserted line end. This makes the clamping element suitable for connection with different conductor diameters.
  • US Pat. No. 4,350,404 describes a clamping element which is formed in one piece from a U-shaped or wavy-folded, electrically conductive and sheet-like substrate.
  • This U or wavy line shape is formed by longitudinal sections running essentially in the longitudinal direction of the line section to be contacted and transverse sections running essentially transverse to the longitudinal direction of the line section to be contacted.
  • Clamping slots for the line section are arranged in the mutually adjacent cross sections, each forming a U.
  • clamping slots of different sizes are formed in the mutually adjacent transverse sections, starting from a common longitudinal section, of which only the clamping slot in the front transverse section is set up for electrically conductive contacting of the line section.
  • the clamping slot in the rear cross section is larger and serves to hold the line section with its insulation.
  • a similar embodiment is described in GB-A-2 018 053.
  • a plurality of transverse sections each with a clamping slot in the longitudinal direction of the line to be connected, are also arranged one behind the other, only the clamping slot in the foremost transverse section being dimensioned so large that it can contact the wire of a line section.
  • the clamping slots in the two rear cross sections serve as a strain relief device.
  • the invention has for its object to design a clamping element of the type specified so that it is also suitable as a plug-in terminal.
  • the clamping element according to the invention has a plurality of clamping slots along the longitudinal extent of the line section to be connected, which have different opening cross sections. It is essential that the clamping slot closest to the inlet opening for the line to be connected has the largest opening cross-section and the opening cross-sections of the further clamping slots decrease in the direction of the inserted line end. This ensures that a conductor with a relatively large cross-section is not squeezed or sheared off at a clamping slot with an opening cross-section that is too small when it is inserted or clamped.
  • the clamping element is formed in a simple manner from a one-piece electrically conductive substrate, in particular a sheet metal strip, which is folded in such a way that the line region to be connected crosses certain sections of the substrate several times and is inserted at the crossing points in recesses in the substrate which form the clamping slots .
  • a first end of the electrically conductive substrate is resiliently bent, and a second end of the electrically conductive substrate is bent such that it encloses the U-shaped end of the substrate and fixes it under a prestress , wherein the second end has openings through which the inner conductor of a connecting wire can be inserted into the plug-in terminal.
  • the clamping element according to the invention is also suitable as a plug-in terminal, a secure plug connection being ensured.
  • Claims 2 to 20 relate to advantageous developments of the invention.
  • the clamping slots can have a taper according to claim 2. This measure ensures that the line section is in contact with the clamping element at two points of contact after the clamping element and the line section to be contacted have been pressed together, as a result of which the contact resistance can be reduced.
  • this taper can be formed by a small v-shaped opening, both the base width and the height of the v-shaped opening being able to be varied in order to vary the opening cross section.
  • the contact between the line and the clamping element can be further improved by a rectangular or trapezoidal extension in the region of the apex of the v-shaped opening.
  • the clamping slot can advantageously have cutting-like edges.
  • the wire to be connected is contacted at four points.
  • a special cutting effect for severing the insulation layer can be achieved by two clamping slots arranged at a short distance behind each other with different opening cross sections.
  • the clamping element can have a plurality of staggered rows of clamping slots arranged to accommodate different electrical lines for parallel connection of several electrical lines according to claims 15 to 17.
  • the terminal according to the invention can be connected according to claims 19 and 20 with a conventional screw, plug, or crimp terminal.
  • the wire ends of the coil formers can be contacted with the connecting terminal according to the invention and the connecting lines with the conventional terminal.
  • Fig. 1 shows a simple embodiment of the clamping element 1 of a terminal according to the invention.
  • two clamping slots 6 and 7 are formed.
  • the clamping slots are implemented as V-shaped recesses.
  • the clamping slots can have any shape, preferably a tapered shape on one side, of a recess.
  • the clamping slots 6 and 7 have different opening cross sections essential to the invention. While cables with a larger diameter are contacted at the larger clamping slot 6, cables with smaller diameters are contacted at the smaller clamping slot 7. It is essential that the clamping slot 6 with a larger opening is on the side facing the line to be contacted.
  • FIGS. 2A and 2B show a transverse section 3 and 4 in front view with inserted line section 10.
  • a compression of the clamping element and the line section 10 causes that at the contact points 11 and 12 an electrically conductive and non-positive connection is established.
  • the insulation skin of the line 10 is cut through at the contact points 11 and 12, and an electrically conductive connection is thus established between the clamping element and the line.
  • an electrical connection can thus be established and there is no need to strip the section of the line to be contacted beforehand.
  • the tapering of the clamping slot causes the line to be contacted to be connected to the transverse section 3, 4 of the clamping element at two support points 11, 12.
  • a slight deformation of the line 10 in the region of the edges of the clamping slot also results in a non-positive connection between the clamping element and the line.
  • FIGS. 2A and 2B Two possibilities for varying the opening cross section of the clamping slots 6, 7 are shown in FIGS. 2A and 2B.
  • the opening cross section of the clamping slots can be changed by varying the base a, b with a constant height h1, h2 of the v-shaped recesses, and on the other hand by varying the height h1, h2 with a constant base a, b.
  • a combination of both measures is also possible.
  • the clamping element 1 is folded in a wave-like or multiply U-shaped manner and can, for example, be formed in one piece from a sheet metal strip.
  • Transverse sections 20 to 26 are arranged transversely to the direction 2 of the longitudinal extent of the line to be contacted, the distances between which are defined by the upper-side longitudinal sections 27 to 30 and the lower-side longitudinal sections 31 to 33.
  • the clamping slots 34 to 40 are arranged on the transverse sections. Are in the illustrated embodiment the clamping slots 34 to 40 are V-shaped and open at the bottom. As already stated, other forms of the clamping slots are also conceivable.
  • the opening cross sections A, A ', B, B', C, C 'and D decrease along the direction 2.
  • the opening cross sections A and A 'of the adjacent clamping slots 34 and 35, B and B' of the adjacent clamping slots 36 and 37 and C and C 'of the adjacent clamping slots 38 and 39 are each identical in pairs.
  • This embodiment has the advantage that the line section to be contacted is contacted at four points, namely at the two points of contact of each of the identical clamping slots. This is particularly advantageous with large currents, since such contacting has a low contact resistance.
  • the clamping gaps 35 and 36 and 37 and 38 and 39 and 40 are also closely adjacent, so that a double clamping slot shown in Figures 4 A and 4 B is formed.
  • the double clamping slot shown in FIGS. 4 A and 4 B has the advantage of an improved cutting effect when cutting through the insulation skin of the conductors to be contacted.
  • the clamping slots 35 and 36 which are arranged at a short distance one behind the other, have different opening cross sections due to a variation in the basic lengths a and b and / or the heights h1 and h2 in the case of a v-shaped configuration.
  • the edge surfaces 50 to 53 of the clamping slots 35 and 36 can be beveled in accordance with the inclination specified by the gradation of the opening cross sections of the clamping slots in order to further improve the cutting effect.
  • clamping slots 34 to 39 As shown in FIG. 5, it is possible to provide, in addition to the clamping slots 34 to 39 already explained with reference to FIG. 3, further, offset clamping slots 60 to 63 on each of the transverse sections of the clamping element 1. In this way, it is possible to connect several lines at one connection terminal and to contact them at the same time by means of only one clamping element and thus to connect them in parallel.
  • the clamping slots 34 to 39 have opening cross sections that decrease along the direction 2. The same applies to the staggered row of clamping slots 60 to 63.
  • the clamping slots arranged on a common transverse section can match in terms of their opening cross-section.
  • the clamping element 1 shown corresponds to the exemplary embodiment shown in FIG. 5 for connecting a plurality of lines in parallel. While a line with a relatively small diameter 70 extends relatively far into the clamping element 1 and is only contacted at the clamping slot 39, a second line 71 with a relatively large diameter is already contacted at the clamping slot 61, which has a larger opening cross section than the clamping slot 39. It can be seen that lines with different cross-sections have to be pushed into the clamping element to different degrees and are contacted at different clamping slots.
  • the clamping slots through which the line passes, but to which it is not contacted have an enlarged opening cross-section compared to the contacting clamping slot, in order to avoid that the line in the area of those not adapted to the relevant line cross-section Clamping slots are squeezed, sheared or even cut.
  • a connecting terminal in addition to the clamping element 1, a connecting terminal according to the invention also comprises a support element (not shown) which, when the clamping element 1 is depressed along the direction 63, offers a corresponding support to the lines 60 and 61, and the connecting terminals are generally surrounded by an insulating housing which is known in various configurations.
  • FIG. 7 shows the development of a sheet metal strip 82 forming a four-stage clamping element.
  • the triangular recesses for the clamping slots 34, 37, 60 and 63 and the diamond-shaped recesses for the clamping slots 35, 36, 61 and 62 can be punched out together with the sheet metal strip.
  • the clamping element is to be folded along the fold lines 75 to 80 shown in broken lines. The manufacture of the clamping element is therefore extremely simple.
  • FIG. 8A to 8D show various further exemplary embodiments of the design of the clamping slots according to the invention.
  • a V-shaped tapering section 6a is initially provided to form the clamping slot 6, to which a rectangular recess 6b adjoins in the region of the apex.
  • the rectangular recess 6a is replaced by a trapezoidal recess 6c, which, however, can also have a triangular shape.
  • the areas 6b and 6c receive the inserted wire and, due to the small angle of attack, cause a relatively large clamping force component in the directions 13a and 13b.
  • the area 6a arranged at the opening of the clamping slots facilitates the insertion of the wires to be contacted.
  • the opening angle of the clamping slot is continuously tapered (6d).
  • the area 6b opposite the opening can be rectangular.
  • a rectangular or insignificantly tapering area in the contact zone of the clamping slot has the advantage that the insulating skin of the wire, in particular the lacquer layer of a enamelled wire, is detached by grinding the conductor along the edge of the clamping slot and in this way the reliable contacting of the conductor is ensured .
  • the embodiment shown in FIG. 6D combines the described advantages of the different zones of the clamping slot.
  • the v-shaped threading area 6a is followed by an area 6e with a constant opening cross section for the safe removal of the insulation skin.
  • the conductor is finally clamped by frictional engagement by means of the force pair 13a, 13b acting on the conductor.
  • the recess 6f in the end region of the clamping slot improves the spring action of the cross section 3 of the clamping element and thus increases the force components 13a and 13b acting on the conductor.

  • the clamping element 1 according to the invention is inserted into an insulation housing 90.
  • the insulation housing 90 has contact surfaces 91 to 95 on which the line sections inserted into the connection terminal lie. When the clamping element and the line section to be contacted are pressed together, these support surfaces absorb the forces acting on the line section to be contacted.

  • the clamping element 1 shown in FIG. 10A differs from the z. B. in Fig. 9A shown clamping element 1 in that the two transverse sections 124 and 125 are extended upward and have further clamping slots 120 to 123 in the area of these extensions.
  • the openings of the upper-side clamping slots 120 to 123 face the openings of the lower-side clamping slots 34 to 36 and 60 to 62.
